Get Lost in the New ‘Maze Runner’ Trailer and Poster

20th Century Fox has released the full-length trailer and new poster for The Maze Runner, based on the novel by James Dashner. Check them out below. Opening in theaters on September 19, the dystopian action thriller stars Dylan O’Brien, Will Poulter, Kaya Scodelario, Thomas Brodie-Sangster, Patricia Clarkson, Aml Ameen, Ki Hong Lee, Jacob Latimore and Chris Sheffield.

In the new trailer, we see young protagonist Thomas (played by Teen Wolf star Dylan O’Brien) as he begins his exploration of the high-walled dangers within the Maze, where he’s arrived after being stripped of his memories. We also get a few tantalizing glimpses of some Grievers, the slug-like creatures whose sting bring both immense pain and long-lost memories. We see a few shots of Teresa (Skins’ Kaya Scodelario), the Glade’s last exile — and its first girl.
